Gang loop wall tie holding bolt

ABSTRACT

A gang loop wall tie holding bolt holding tie rods of multiple panel units in gang form sections for pouring concrete has a body portion from which extend laterally in the same direction a finger to extend through adjacent frame members of adjacent panel units. Spaced from this finger is a shorter medial extension having a hole therethrough and spaced from the medial extension at the other end of the body portion is a tie rod receiving stud offset from the plane of the finger and medial extension. The body portion may be reinforced by forming a longitudinally extending partial corrugation therein, ending short of the ends of the body portion and having an extension directed toward the medial extension.

GANG LOOP WALL TIE HOLDING BOLT BACKGROUND OF THE INVENTION The use ofprefabricated panels in a gang of formed sections either preassembled orassembled on the job is well known in the concrete pouring art. Suchprefabricated units usually have a flat face of plywood or othersuitable material of appropriate dimensions reinforced by a metal frameextending around the periphery of each unit. The metal frame is usuallyof H-shape cross-section and edges thereof abut when the panel units arein position. These edges are suitably cut away to provide space for theinsertion of tie rods to extend between spaced gang form sectionsbetween which the concrete is to be poured. The tie rods prevent theweight of the concrete from forcing the gang form sections away fromeach other.

Gang form bolts for locking adjacent sections together and for holdingthe looped ends of the tie rods have heretofore been proposed and theiruse described as in US. Pat. No. 3,067,479, granted Dec. 11, 1962, to V.R. Schimmel and entitled Panel-Securing Tie Rod Anchor Bolt With OffsetAnchor Point.

SUMMARY OF THE INVENTION A tie rod anchor bolt comprises a body portion,a fin ger extending from one end of the body portion to pass throughslots in adjacent frame members of panel units, a medial extensionextending from said body portion in the same plane and in the samedirection as said finger and spaced therefrom, an opening in said medialextension and a tie rod receiving stud extending from the other end ofthe body portion parallel to the finger and to the medial extension andoffset from the plane thereof, the body portion being reinforced by acorrugation terminating short of the ends of the body portion and havingan extension toward the medial extension, a metallic pin passing throughthe aperture in the media] extension to hold the bolt in place andprevent the looped end of the tie rod from leaving the tie rod receivingstud.

BRIEF DESCRIPTION OF THE DRAWINGS In the accompanying drawings, in whichlike reference characters indicate like parts, FIG. 1 is a view fromabove of a tie rod bolt of the present concept showing the relationshipof the body portion to the ex- 7 tending finger, medial extension andtie rod receiving stud;

FIG. 2 is a view from the right of the embodiment of FIG. 1;

FIG. 3 is a view of the embodiment of FIG. 1 shown in position forinsertion from left to right through adjacent frame members of adjacentpanels showing the position of the tie rod loop;

FIG. 4 shows the bolt of FIG. 3 in position after movement from left toright and engaging the frames of adjacent panels with a nail holding thebolt and tie rod in position;

FIG. 5 is a view of the bolt of FIG. 1 in position for movement fromright to left into position to engage the tie rod and the position ofthe loop end of the tie rod; and

FIG. 6 is a view of the bolt of FIG. 5 with the bolt in positionengaging in the frames of adjacent panels with the tie rod and bolt heldtogether by a nail.

DESCRIPTION OF THE PREFERRED EMBODIMENT As seen in FIGS. 1 and 2, thetie rod bolt has a body portion 10 provided with a finger 11 extendingin the principal plane thereof and a medial extension 12 spaced fromfinger l1 and in the plane of finger 11. A tie rod receiving stud 13 isspaced from extension 12 and extends parallel thereto and to finger l1.Stud 13 is offset from the plane of finger 11 and extension 12 as seenin FIG. 2. Extension 12 is provided with a through opening 14 to receivea pin or nail or broken end of a tie rod.

Body 10 is provided with a raised corrugation l5 having an extension 16extending toward medial extension 12 for strengthening purposes.

A slot 17 is provided in body 10 adjacent the base of medial extension12 adjacent finger 11.

Referring now to FIGS. 3 and 4, the tie bolt there being disposed forinsertion from left to right through frames 18 and 19 of panels 20 and21, respectively, frames 18 and 19 being provided in known manner, withhalf slots or openings 22 and 23, respectively, to receive a tie rod 24having a conventional looped end 25. Frames 18 and 19 are also providedwith mating opening 26 and 27 respectively, in known manner to receivefinger 11 of the bolt.

The tie bolt is held with corrugation 15 facing down and finger 11 isentered in openings 26 and 27. The tie bolt is moved to the right untilloop 25 passes over stud 13, the flat portion of the loop being disposedbeneath stud 13. Medial portion 12 then passes over tie rod 24 and a pinnail or broken end of a tie rod 28 is then inserted through opening 14to hold the bolt and tie rod together and in position so that stud 13cannot disengage from loop 25 and finger 11 disengage from frames 18 and19, the adjacent flange of frame 18 fitting into slot 17.

Referring now to FIGS. 5 and 6, the tie bolt is to be inserted throughopenings 26 and 27 of frames 18 and 19 from right to left. In this casethe bolt is held with corrugation 15 upward and tongue 11 is slid intoopenings 26 and 27 until stud 13 enters loop 25 and extension 12 liesunder tie rod 24. The flat part of loop 25 then lies on top of stud 13.Pin 28 is then entered through opening 14 to hold the elements inposition, as above, and the adjacent flange of frame 19 enters slot 17.

The tie bolt does not function to lock frames 18 and 19 together, thisbeing done by conventional wedge bolts, not shown. 7

Variations to the above-described preferred embodiment of the presentinvention may be made without departing from the inventive concept.Reference should therefore be had to the appended claims to determinethe scope of this invention.
